14100
Step-by-step explanation:
Answer:
750
Step-by-step explanation:
The big showroom has an area of 0.25 million sq. ft.
In the last summer sale, it is surveyed that the population density was 0.003 people per sq. feet and that included all the people in the building.
Therefore, the number of people who attended the summer sale at this showroom on that day was (0.003 × 0.25 × 1000000) = 750. (Answer)
{Since 1 million = 1000000}
Answer:
<h2>=3,798,000 people</h2>
Step-by-step explanation:
<h2>if 100%=240,000</h2><h2>therefore 100+5.5=105.5%</h2><h2>105.5÷100×240,000</h2><h2>=253,000</h2><h2>15×253,000</h2><h2>=3,798,000</h2>
Answer:
x = 4 ±9i
Step-by-step explanation:
x^2 - 8x + 97 = 0
Complete the square by subtracting 97 from each side
x^2 - 8x =- 97
Take the coefficient of x
-8 and divide by 2
-8/2 = -4
Then square it
(-4)^2 = 16
Add it to each side
x^2 - 8x + 16 = -97+16
(x-4)^2 = -81
Take the square root of each side
x-4 = ±sqrt(-81)
x-4 = ±9i
Add 4 to each side
x = 4 ±9i
